“The advocates will say the land is a drop within the bucket within the state,” mentioned Sara Alden, a Middle Level mother who began the web site Iowa for Accountable Photo voltaic.

Whereas most People proceed to help increasing photo voltaic (84 %) and wind farms (77 %), Republicans and Democrats have turn out to be extra divided, the Pew Analysis Middle reported in June 2021.

Almost 60 % of Iowa’s electrical energy comes from wind — the most important share within the nation.

MidAmerican has greater than 3,400 wind generators throughout the state, with most concentrated in western and central Iowa. These wind farms generate sufficient electrical energy to energy 2.3 million households a 12 months, the firm reported. An evening drive alongside Interstate 80 from Iowa Metropolis to Des Moines reveals an horizon blinking with pink lights marking the tops of wind turbine towers.

However not like wind farms developed within the Nineties to 2010s, newer installations have drawn extra criticism in Iowa. Information headlines make clear Iowans’ issues with wind:

Photo voltaic myths versus realities

Delusion: Photo voltaic panels enhance flood threat

Actuality: Rain runs off photo voltaic panels the identical manner it does off any flat or sloped floor, draining to floor beneath. A 2013 examine within the Journal of Hydrologic Engineering mentioned “modeling confirmed that the photo voltaic panels themselves didn’t have a big impression on the runoff volumes, peaks or instances to peak.” The examine does go on to say grass beneath photo voltaic farms needs to be “properly maintained” to keep away from erosion.

Delusion: Photo voltaic farms are loud.

Actuality: The one sound from photo voltaic farms is a low buzzing from inverters when vitality is being transformed from the solar. The Massachusetts Division of Power Assets discovered the noise was inaudible 50 to 150 toes from the sting of the photo voltaic arrays.

Delusion: Photo voltaic panels create glare.

Actuality: Most photo voltaic farms are photovoltaic, which use non-reflective glass designed to soak up, not mirror, gentle with a purpose to make vitality.

Delusion: Photo voltaic panels solely work on sunny days.

Actuality: Extra daylight means extra vitality technology from photo voltaic panels. However photo voltaic panels nonetheless take in solar on cloudy days, notably if the clouds are increased and thinner, the Nationwide Oceanic and Atmospheric Administration reported.

Delusion: Photo voltaic produces harmful electrical and magnetic fields.

Actuality: Photo voltaic arrays create the identical degree of electromagnetic fields as electrical home equipment and wiring present in most homes and buildings, the Massachusetts Division of Power Assets reported. Measurements at three photovoltaic arrays in Massachusetts present off-site electromagnetic exposures had been lower than .05 milligauss — 3 mG is the bottom publicity degree seen to have potential well being results.

Quietly powering a constructing or a farm or a home, early photo voltaic initiatives in Iowa sparked preliminary curiosity earlier than turning into a part of the Iowa panorama.

However as Iowa utility corporations search to make solar energy an even bigger a part of the vitality combine — spurred by the necessity to restrict greenhouse gases to scale back the impacts of local weather change — proposed photo voltaic installations have grown in measurement and quantity, inflicting extra pushback from neighbors.

Among the issues are primarily based on misinformation — photo voltaic panels don’t enhance flood threat or trigger harmful glare — however some opponents have reliable questions on how utility-scale photo voltaic initiatives will have an effect on their pockets of rural Iowa.

“The advocates will say the land is a drop within the bucket within the state,” mentioned Sara Alden, a Middle Level lady who began the web site Iowa for Accountable Photo voltaic.

A proposed 200-megawatt photo voltaic set up by Palo is close to Alden’s house in western Linn County. The NextEra Power mission is slated to make use of about 1,200 acres of land. Not a lot when you think about Linn County is 460,000 acres — however as extra neighbors promote their land to NextEra, Alden worries concerning the impression.

“Rolling hills, a number of bushes. The highway is known as Inexperienced Grove for a motive,” Alden mentioned. “My husband and I’ve a dream to reside within the nation. We sacrificed rather a lot to economize to purchase a little bit land and construct a home and now we’re being industrialized.”

There is also new politicization of wind and photo voltaic vitality.

Whereas most People proceed to help increasing photo voltaic (84 %) and wind farms (77 %), Republicans and Democrats have turn out to be extra divided, the Pew Analysis Middle reported in June 2021.

Greater than 90 % of Democrats and left-leaning independents help photo voltaic and wind, Pew reported. However amongst Republicans and Republican-leaning survey respondents, help for solar energy went from 84 % in 2020 to 73 % in 2021, Pew reported. Help for wind dropped from 75 % in 2020 to 62 % a 12 months later.

Renewable vitality

MidAmerican Power has a purpose of offering 100% renewable vitality to its prospects by 2025. Alliant Power desires to have internet zero carbon emissions from the electrical energy the corporate generates by 2050.

Electrical energy technology in the USA in 2020 resulted in 1.55 billion metric tons of carbon dioxide, which equaled about 0.85 kilos of CO2 emissions per kilowatt-hour of vitality produced, in accordance with the U.S. Power Data Administration.

U.S. energy vegetation that burned coal, pure gasoline and petroleum had been the supply of about 62 % of U.S. electrical energy technology in 2020, however accounted for 99 % of power-related carbon dioxide emissions. The company considers electrical energy from renewable sources, together with wind, photo voltaic, hydro and biomass, to be carbon impartial.

Saving the planet isn’t the one motivation for utilities; a lot of their industrial prospects are insisting on cleaner energy.

Wind energy

Wind energy got here to Iowa properly earlier than photo voltaic, with a 1983 invoice requiring investor-owned utilities in Iowa to buy wind energy.

Then-Gov. Terry Branstad, a Republican, advocated for wind energy within the Eighties and thru 2016, when he acknowledged it in his Situation of the State deal with as a manner for farmers to become profitable from turbine lease funds.

Almost 60 % of Iowa’s electrical energy comes from wind — the most important share within the nation.

MidAmerican has greater than 3,400 wind generators throughout the state, with most concentrated in western and central Iowa. These wind farms generate sufficient electrical energy to energy 2.3 million households a 12 months, the corporate reported. An evening drive alongside Interstate 80 from Iowa Metropolis to Des Moines reveals an horizon blinking with pink lights marking the tops of wind turbine towers.

Alliant owns and operates 1,299 megawatts of wind technology in Iowa, which is sufficient to energy greater than 500,000 properties, the corporate reported.

However not like wind farms developed within the Nineties to 2010s, newer installations have drawn extra criticism in Iowa. Information headlines make clear Iowans’ issues with wind:

• “Wind generators haven’t been universally welcomed by everybody in Iowa” — The Gazette, Feb. 23, 2019

• “Report: Sound from wind generators doesn’t hurt human well being” — The Gazette, Jan. 31, 2019

• “‘Sparkles’ and ‘stray voltage’: Why these Iowans actually, actually hate wind energy“ — Des Moines Register, April 21, 2017

Native ordinances

With half of Iowa’s 99 counties having utility-scale wind farms in operation or growth by 2017, the Iowa Environmental Council reported, greater than half of Iowa’s counties now have guidelines for siting, security, infrastructure wants and decommissioning generators.

The council recommends minimal setbacks from residential properties of 1,000 to 1,250 toes and limits on turbine sounds of no decrease than 50 dBA (decibels weighted for the human ear).

“For counties interested by attracting the entire native advantages that include wind technology, a well-drafted and balanced wind siting ordinance is a crucial preliminary step,” the environmental group wrote. “Our evaluation of county ordinances throughout Iowa reveals that many counties have adopted workable ordinances leading to profitable native wind growth.”

Cerro Gordo County in north-central Iowa — which has had wind generators because the late Nineties — has a particular use allow that applies to utility-scale wind or photo voltaic farms and cell towers, Planning and Zoning Administrator John Robbins mentioned.

It features a fundamental setback of 1 foot of distance for each foot of peak. However county leaders can layer on further necessities relying on the proposed mission.

“In recent times, it (wind) has turn out to be a little bit extra of a NIMBY,” he mentioned, referring to the phrase, not in my yard. Robbins famous it appears as if private politics play extra of a job in individuals’s opinions about wind and photo voltaic.

Invenergy, a multinational energy firm primarily based in Chicago, desires to construct an 180-megawatt wind farm in Cerro Gordo County, with 40 to 50 generators from the Floyd County line all the way in which west to Mason Metropolis, the Mason Metropolis Globe Gazette reported.

Landowners who spoke at a February assembly wished to know precisely the place Invenergy wished to place every turbine, however the firm mentioned it desires to signal voluntary easements after which chart a path for the towers.

If the county’s special-use allow works as supposed, the setbacks needs to be sufficient to scale back group issues, Robbins mentioned.

The county additionally has labored with builders to scale back shadow flicker — when the solar is low on the horizon and casts rays by means of the turbine blades — by correct siting and, in some instances, timers, he mentioned.

Robbins hopes the county’s allowing course of additionally will work to manage utility-scale photo voltaic installations, which haven’t but come to Cerro Gordo County.

Subsequent up: photo voltaic

However photo voltaic is heating up in Iowa.

“MidAmerican simply began creating photo voltaic final 12 months,” mentioned Adam Jablonski, the corporate’s vp of useful resource growth. MidAmerican solely has 5 photo voltaic initiatives, together with a 3-megawatt facility opened in Hills earlier this 12 months.

The Hills website was on land MidAmerican already owned. The corporate did an environmental examine after which went by means of the design and allowing course of. The utility began development in spring 2021 and opened the set up in early 2022.

“That one was fairly clean crusing,” Jablonski mentioned. “We bought good help from the county. We talked with the adjoining landowner to verify he was conscious of it. He had no issues.”

Even with a bigger mission, the 117-megawatt Holliday Creek Photo voltaic Venture in Webster County, slated to be totally operation in 2022, MidAmerican has not encountered vital resistance, officers mentioned.

Photo voltaic myths versus actuality

Delusion: Photo voltaic panels enhance flood threat

Actuality: Rain runs off photo voltaic panels the identical manner it does off any flat or sloped floor, draining to floor beneath. A 2013 examine within the Journal of Hydrologic Engineering mentioned “modeling confirmed that the photo voltaic panels themselves didn’t have a big impression on the runoff volumes, peaks or instances to peak.” The examine does go on to say grass beneath photo voltaic farms needs to be “properly maintained” to keep away from erosion.

Delusion: Photo voltaic farms are loud.

Actuality: The one sound from photo voltaic farms is a low buzzing from inverters when vitality is being transformed from the solar. The Massachusetts Division of Power Assets discovered the noise was inaudible 50 to 150 toes from the sting of the photo voltaic arrays.

Delusion: Photo voltaic panels create glare.

Actuality: Most photo voltaic farms are photovoltaic, which use non-reflective glass designed to soak up, not mirror, gentle with a purpose to make vitality.

Delusion: Photo voltaic panels solely work on sunny days.

Actuality: Extra daylight means extra vitality technology from photo voltaic panels. However photo voltaic panels nonetheless take in solar on cloudy days, notably if the clouds are increased and thinner, the Nationwide Oceanic and Atmospheric Administration reported.

Delusion: Photo voltaic produces harmful electrical and magnetic fields.

Actuality: Photo voltaic arrays create the identical degree of electromagnetic fields as electrical home equipment and wiring present in most homes and buildings, the Massachusetts Division of Power Assets reported. Measurements at three photovoltaic arrays in Massachusetts present off-site electromagnetic exposures had been lower than 0.05 milligauss — 3 mG is the bottom publicity degree thought of to have potential well being results.

However two large-scale photo voltaic developments in Linn County have confronted open opposition from some neighbors.

Clenera and CIPCO introduced in April 2021 their plan to open an 100-megawatt photo voltaic mission close to Coggon. Linn County Planning and Zoning in November voted 6-to-1 towards rezoning agricultural land to permit for the photo voltaic farm.

This was after some neighbors expressed concern about taking farmland out of manufacturing, the seems to be of photo voltaic farms, decreased property values and the county’s capacity to implement ordinances.

“Cornfields are simply as vital to me as oceanfront property,” Greg Bickal, proprietor of Bickal Koi Farm, mentioned at a public assembly final 12 months. “That is my retirement property, and I’ve dreamed of this and now I’m going to be surrounded by photo voltaic panels on three sides.”

The Linn County Board of Supervisors voted 2-to-1 in January to permit Coggon Photo voltaic to proceed. The location is anticipated to be operational by 2023.

Iowa for Accountable Photo voltaic’s Alden opposed Coggon Photo voltaic and she or he’s towards the NextEra mission close to Palo. However she makes clear she’s not towards photo voltaic in all conditions.

“We’ve tons of concrete parking garages, rooftops. Why are we not using that house?” she mentioned. “To show productive prime farm floor right into a part-time electrical technology facility is simply not accountable.”

MidAmerican’s Jablonski mentioned rooftop photo voltaic initiatives normally are smaller scale and panels normally don’t transfer to trace the solar, which lowers productiveness.

MidAmerican is aware of Iowans are involved about taking agricultural land out of manufacturing, however says these initiatives are only a sliver of Iowa’s farmland. A MidAmerican sister firm in California permits sheep grazing at a photo voltaic set up, and initiatives additionally could be habitat for bees and different pollinators.

There nonetheless is comparatively little analysis on the impression photo voltaic farms have on close by property values. One examine in Massachusetts and Rhode Island, extra densely populated than Iowa, prompt homes inside one mile depreciate 1.7 % following development of a photo voltaic array.

A 2018 report by the College of Texas Austin mentioned a “geospatial evaluation reveals that comparatively few properties are prone to be impacted.”

Politics divide on renewables

Republicans are greater than twice as seemingly as Democrats (65 % to 30 %) to say wind and photo voltaic are unreliable, the Pew Analysis Middle examine discovered. Republicans additionally usually tend to say wind and photo voltaic price greater than different vitality sources.

Greater than 80 % of Democrats say producing energy from wind is best for the setting, in comparison with 45 % of Republicans, Pew discovered.

And the place Branstad touted Iowa’s management in wind, his successor, Gov. Kim Reynolds, additionally a Republican, has not talked about the state’s wind rating in latest Situation of the State addresses. As an alternative, she promotes corn-based ethanol and biodiesel.

Greater than 2,800 individuals have signed an internet petition on the Iowa for Accountable Photo voltaic web site.

Belinda Scott, of Cedar Rapids, wrote on the positioning that she desires NextEra to seek out one other spot for the photo voltaic farm, proposed for land close to the Duane Arnold Power Middle, a nuclear facility that began its decommissioning course of in 2020.

“There may be loads of land round to make use of with out tearing up a neighborhood and uprooting households,” Scott wrote. “Households have already been torn by the closing of this plant! There are extra vital issues than cash! Discover one other place!”

Jablonski mentioned builders and utility corporations can take steps to make photo voltaic installations much less noticeable. By a 3-megawatt photo voltaic set up in Waterloo, MidAmerican planted bushes alongside the sting of the property to offer screening for neighbors, Jablonski mentioned.

Whereas some communities need to conceal photo voltaic initiatives, Johnson County officers are excited by the prospect of an 150-megawatt set up being on show alongside Freeway 218 south of Iowa Metropolis.

The Johnson County Photo voltaic Triangle, proposed for 1,200 acres, is below evaluation by the Midcontinent Impartial System Operator, MISO, which manages the ability grid throughout 15 states and a Canadian province.

“I believe it’s a extremely nice speaking piece for the county when they’re recruiting employers, builders, tech corporations and future corporations,” mentioned Sean Kennedy, associate at Megawatt Photovoltaic Improvement Inc. “We’re erasing a big piece of that carbon footprint in Iowa.”

Tom Banta, director of strategic progress for the Iowa Metropolis Space Improvement Group, agreed when The Gazette interviewed him in 2021.

“It doesn’t get us to 100% renewable, however it will get us nearer that manner and turns into a advertising software for companies which are searching for that,” he mentioned.
